Comparison of Papillary Balloon Dilatation Vs.Sphincterotomy for Lithotripsy in Difficult Sphincterotomy or Distal CBD Tapering

• Conditions: Choledocholithiasis

• Registration Number: NCT00329888
• Lead Sponsor: National Taiwan University Hospital

Brief Summary

Compare endoscopic papillary balloon dilatation vs. endoscopic sphincterotomy for bile duct stones in:

* when sphincterotomy is difficult (periampullary diverticulum, prior sphincterotomy or Billroth II anastomosis)

* when there is distal CBD tapering.

Detailed Description

Endoscopic papillary balloon dilatation is an alternative to endoscopic sphincterotomy for treating bile duct stones:

* easier and as effective. But...

* a higher risk of pancreatitis.

Conditions including periampullary diverticulum, prior EST, Billroth-II anastomosis, or distal CBD tapering pose difficulty in EST and lithotripsy with increased risk of complications.

Whether EPBD or EST is superior in efficacy or safety under such circumstances is not clear.
